one skilled in the art can make and use the sime.

My invention relates to the art of finishing cotton warp-yarn; and it has for its object the removal, or, perhaps, more properly, the suppression, of the fine ends that give to the entire surface of such yarn finished in the old mixtures a fuzzy character and softness that are objectionable; and its object is, further, to

increase the elasticity, flexibility, and durae bility of the yarn treated with my improved finishing mixture; and to these ends my improvement consists in treating cotton warpyarn in a solution of starch, tallow, molasses, and Epsom salts, and in the solution compounded of the said ingredients, as more particularly hereinafter described, and pointed out in the claims.

In the practice of my improvement a mixture is prepared by dissolving, preferably and usually in boiling water of about sixty gallons in quantity, fifty pounds of starch, five pounds of tallow, three quarts of molasses, and ten pounds of Epsom salts,and thoroughly stirring them together. The warp-yarn after being colored is treated in this mixture until well saturated,and is then removed and dried in the usual manner, as in a centrifugal drier or on hot cylinders. By the use of the molasses and the Epsom salts in the above mixture and in the manner described material and valuable advantages accrue, and the proportions of the several ingredients may be varied to a considerable degree, although the proportion stated is substantially that used and preferred by me. I

One of the advantages of the yarn finished by my improvement is, that it is more elastic than when finished in the old'ways, and so much so that but few breaks occur in weaving, while afurther advantage is found in the fact that the yarn wears smooth with a hard glossy finish, and this facilitates weaving.

WVhen yarn finished in the old mixtures has been colored black and is packed away, it is found that it deteriorates rapidly, so that when such yarn is a year or two old it has be come tenderthat is, will break under such slight strains as to render it useless. On the contrary, yarn finished with my improved mixture is rendered more durable, and will not become weak and tender even when dyed and stored for many months.

I claim as my imp.rovement- 1. The within-described method of finishing cotton yarn,that consists in treating it in bulk in a solution of starch, tallow, Epsom salts, and molasses, all substantially as described.

2. An improved finishing mixture for cotton yarn, consisting of a solution in water of starch, tallow, Epsom salts, and molasses, in
